Criminal justice client rehabs are available being a considerably better option than incarceration or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been found guilty of dui of drugs or alcohol may be eligible for rehab services because of their problem as opposed to serving time in jail. The judge might even order that the individual receive rehab, either alone or in addition to other consequences. Very first time offenders in particular tend to be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have better possibility of remaining out of the system following rehabilitation.
